BHL Series
Hengchun Actuator’s BHL Series Long Stroke Pneumatic Actuator is a high-performance linear pneumatic drive engineered for industrial automated equipment, designed exclusively to deliver large linear displacement (typically over 200 mm, extendable to several meters). As a core product of our Pneumatic Actuators portfolio, it is optimized for long-stroke and medium-to-high load working conditions, serving as a superior alternative to traditional hydraulic or electric cylinders. This actuator integrates clean pneumatic power, high transmission efficiency and cost-effectiveness, becoming a reliable linear drive solution for large-range linear motion operations across diverse industrial sectors.
The actuator excels in large-range linear actuation, with a standard displacement exceeding 200 mm and customizable extension to several meters. Meeting the most demanding long-distance linear motion requirements in industrial settings.
Powered by pneumatic energy, it achieves fast response and stable output. While its manufacturing and operational costs are far lower than hydraulic and electric cylinder solutions under the same working conditions.
Tailored for medium-to-high load scenarios. It provides consistent output force across varying working pressures (2-8 Bar), adapting to diverse industrial actuation needs.
As a pneumatic drive system, it produces no oil leakage or secondary pollution. Requiring minimal routine maintenance and reducing industrial operational downtime.

Hengchun Actuator is an ISO certified manufacturer, and all Long Stroke Pneumatic Actuator (BHL Series) products comply with international industrial standards and feature explosion-proof design for high-risk working environments. Our strict Manufacturing & Quality control process covers raw material inspection, production assembly and finished product testing, with each actuator undergoing pressure and performance calibration before delivery. Backed by global quality management systems and professional R&D, we ensure long-term stability and durability of the BHL Series in continuous industrial operation.
Ideal for pushing, pulling, lifting and door opening operations that require large linear displacement, such as industrial heavy-duty door actuation and large-scale material handling equipment.
Serves as a drive component for pipeline valves and emergency shutdown devices, adapting to the harsh working conditions of the oil and gas sector with its explosion-proof and stable performance.
Applied in power generation equipment adjustment and water/wastewater treatment system actuation, meeting the high reliability requirements of public utility industries.
Used for feeding, positioning and material transfer in automated industrial equipment, improving production line efficiency with fast and accurate linear motion.
The standard linear displacement is over 200 mm, and the displacement can be extended to several meters according to custom industrial requirements, matching different long-stroke actuation needs.
